Definitions

  • ABSTRACT A frame assembly for a scraper-chain conveyor and having two parallel side walls attached together with transverse walls.
  • the side walls have apertures therein for receiving bearings of a chain drum or wheels.
  • One or more horizontal wall is welded between the side walls and a plurality of upright reinforcing ribs are in turn welded to the horizontal wall.
  • the rib nearest the apertures carries a chain deflecting/guiding member.
  • a plate adjustable in relation to the side walls, is pivotably supported at the end of the assembly for attachment to a conveyor.
  • the plate is inclined in relation to the horizontal wall and the ribs are located between the plate and the horizontal wall.
  • the plate is supported on adjustable eccentrics or the like used to enable the position of the plate to be altered in accordance with the diameter of the drum or wheels accommodated by the assembly.
  • the present invention relates to a frame assembly for use with scraper-chain assemblies employed in mineral mining.
  • Frame assemblies for conveyors are known in which a plate, which adjoins the conveyor floor, is mounted between two'parallel side walls. This plate is normally welded to the side walls and material transferred along the conveyoris then conveyed over the plate and discharged over a chain drum or wheels rotatably supported between the side walls. From time to time chain drums or wheels of different diameter are employed and this necessitates that the entire frame assembly be replaced.
  • a frame assembly for use with a scraper-chain conveyor; said assembly comprising side walls adapted to rotatably mount a chain drum or chain wheels therebetween, and a plate mounted between the side walls and movable in relation to said walls to various positions.
  • the aforesaid plate constitutes a floor which forms a continuation of the conveyor floor.
  • the invention also provides a frame assembly for use with scraper-chain conveyors; said assembly comprising a. two parallel side walls;
  • the plate is pivotably supported in the region of one end of the assembly and there is provided adjusting means for raising and lowering the end of the plate remotefrom said one end.
  • the one end of the assembly would be mated up to the conveyor.
  • the adjusting means can be one or more eccentric members rotatably supported by one or both side walls.
  • the assembly may also have a further plate attached between the side walls to lie beneath the firstmentioned plate and a plurality of upright ribs attached tosaid further plate and extending towards said firstmentioned plate.
  • the rib remote from the one end of the assembly may accommodate one or more chain deflecting/guiding members of conventional type.
  • the further plate is substantially horizontal and the first-mentioned plate is inclined in relation thereto in all its possible adjustment positions.
  • FIG. 1 is a schematic partly-sectional side view of a frame assembly made in accordance with this invention.
  • FIG. 2 is a schematic perspective view of the assembly.
  • the frame assembly depicted in the drawing would normally be attached to one end of a scraper-chain conveyor of the known type having side walls adjoined by a horizontal floor and a scraper-chain assembly circulated along the floor.
  • the end section of the conveyor is shown schematically in dotted outline denoted 50 in FIG. 2.
  • the frame assembly is a self contained construction with two parallel side walls 10 rigidly interconnected by transverse walls which are preferably welded to the walls 10.
  • the walls 10 have aligned circular apertures 11 therein for receiving bearings for a chain drum and/or chain wheels rotatably mounted between the walls 10.
  • a drum 30 may be rotatably mounted between the side walls 10 to drivably engage a scraper-chain assembly 31 of the conveyor so that the chain assembly is entrained around the drum 30 in known manner.
  • a transverse floor plate 12 is welded between the walls 10 and is disposed in a substantially horizontal disposition.
  • the plate 12 in turn, has welded thereto upright ribs 13,14,15 which act as reinforcements and these ribs are also welded to the walls 10.
  • the ribs 13,14,15 progressively increase in height towards the drum so that the rib 15 is of greater height than the rib 13.
  • Chain guiding/deflecting members 16 of conventional type are attached to the rib 15 so as to project towards the drum.
  • a rod 17 forming a pivot joint is disposed between the walls 10.
  • a plate 18 is pivoted about this joint so that the end 18' of the plate 18 can swing in a vertical plane between the walls 10.
  • the plate 18 extends substantially over the entire width between the walls 10 and if desired sealing strips 20 can be used to seal the gaps between the plate 18 and the walls 10.
  • Means is provided to effect an adjustment of the position of the plate 18 and in this example this means takes the form of two eccentric members 19 rotatably sup ported by the walls 10 and engaging the plate 18 so as to support the latter.
  • the members 19 are mounted on spindles 32 accessible externally of the side walls 10 and by rotating the members spindles 32 and hence the 19 the end 18' of the plate 18 can thus be raised or lowered to conform to the particular size of drum or chain wheels used.
  • the end 18 would usually be moved by something in the order of 2.4 cm.
  • eccentric members 19 instead of employing eccentric members 19 to adjust the position of the plate 18 it is possible to use a displaceable wedge-shaped component or push-in bolts.
  • a frame assembly for use with scraper chain conveyors comprising a. two parallel side walls;
  • said means for spacing comprises a substantially horizontal plate which lies beneath the first-mentioned plate and further comprising a plurality of upright ribs attached to said horizontal plate and extending towards said first-mentioned plate.
  • pivoting and adjusting means is in the form of at least one eccentric member engaging the underside of the plate and carried by a spindle supported for rotation between the side walls.
  • a frame assembly for mine installations which assembly comprises two spaced side walls, means for mounting replaceable chain locating means between the side walls and a floor plate disposed between the side walls, the floor plate having one end adjacent said mounting means and the other end terminating remote from said mounting means and adjacent end portion of the side walls; the improvement comprising means for pivotably supporting said other end of the floor plate between the side walls and means for pivoting and adjusting the inclination of the floor plate whereby, in operation, to guide a scraper-chain assembly onto said chain-locating means.
  • a mineral mining installation comprising a longwall conveyor composed of side walls adjoined by a floor and a scraper-chain assembly for moving along said floor, a frame assembly disposed at one end of the conveyor, said assembly having side walls disposed substantially co-planar with the side walls of the frame assembly and having the scraper-chain assembly entrained therearound; a floor plate disposed between the side walls of the frame assembly and having one end forming a continuation of the conveyor floor, means for supporting the floor plate for pivotal movement about said one end and means for pivoting said floor plate to raise or lower the other end of the plate remote from said one end.
